HoneywellRA89A1074 Switching Relay, 24V

These Honeywell switching relays seem to work fine. They are really much more robust than I needed for the job I have them doing, but they turn on and off the pump as I wished based on thermostat settings. They do have a high pitch hum when they are first energized that is fairly noticeable. This seems to go away after a while... or I am just getting used to it as white noise. All in all a very good purchase.

This product is the mechanism behind my thermostat. It does exactly what it’s supposed to do and does it silently.

Fixed my problem. My zone 3 was intermittently working. I could hear a buzz from my relay. Ended up replacing it and now it works perfectly.

Part worked perfectly. Was exactly as described. Wasn't available at local appliance parts store. Was shipped quickly.

Matched my 40 year old heating system perfectly, same design and function and almost identical to original, delivered even before promised, and easily installed to replace one of two relays part of my hot water heating system.

Product as advertised

works this was for stock looks like new

The part was correct and good condition

Replaced my fan limit switch with this relay to control fan of a thermostat. Easy to install. Ony concern right now is the loud buzz that it creates. Hopefully it will stop or will ask for a replacement

works great, very easy to install
